If, like most people, I had given up and thought, "Is everyone else living like this?" or "I'm already a senior in college, isn't it too late to start over?", I might have graduated from engineering school and lived the life of an ordinary office worker, doing things I hated every day.
But I didn't want to live like that.
In the last semester of my senior year of college, with a storm of worries in my mind, while my classmates were busy preparing for employment, I decided to take the CSAT again.
When I can't focus on my studies because of my anxious mind, there is a spell I recite to myself.
"Let's just sit at the desk for an hour." With the thought that if I don't sit at the desk, pick up a pen, and study right now, "I'll just have to live the same life I did yesterday," I focused on my studies, and gradually, I started to gain momentum.
(Omitted) Although it was a short six-month exam preparation period, I took the CSAT without any regrets by maximizing my explosive concentration that came from my desperate desire to change my life, and was accepted to Seoul National University Medical School on the first try.

I studied for the college entrance exam during my final semester of my senior year of college, and after graduating from medical school, I worked as a doctor at a hospital during the day and prepared for the entrance exam for dental school at night.
Because I was preparing for the exam while balancing school and work, I was always short on time.
That's why I had to study efficiently by making 200% use of the time given to me.
The fact that he was able to pass the national medical and dental exams, which are known for their enormous amount of studying, with excellent scores on the first try was also because he optimized his exam preparation by focusing on 'studying to pass' rather than 'studying for the sake of studying.'
It is a big mistake for long-term students to think that only those who memorize everything and have a heavy butt will pass.
The '3x Speed ​​Study Method' introduced in this book is a strategy for passing the exam that encompasses all the know-how I gained from my life as a test taker.
For those of you who are struggling at your desk today to create a tomorrow different from yesterday, this book will be the 3x faster cheat key to passing the exam.

When I was attending Seoul National University's School of Dentistry and studying for the national dental licensing exam, I was 36 years old.
I could feel with my whole body that my physical strength and learning ability had declined incomparably compared to when I was in my 20s.
In addition, to earn tuition and living expenses at the time, I had to complete a difficult practical training schedule at a dental hospital during the day, and after 5 p.m., I went to a nursing hospital and worked night shifts to care for hospitalized patients.
In fact, it was the worst possible situation for studying for the national exam.
(Omitted) So the solution I came up with was to squeeze out more spare time.
Although I couldn't open my books and study comfortably during the week, I made the most of my spare time while working as a dental hospital intern.
The method was to review what I studied in the evening during spare time the next day.

Many people ask me about how many hours I study each day.
"How many hours a day should I study?", "How many hours a day should I focus on studying to be effective?" I've heard these questions countless times, and here's how I confidently answer them.
First, don't put too much meaning into the study time itself.
Second, if you can concentrate and study for several hours straight, that's great, of course. But if you don't have the ability or will to maintain that level of concentration for long periods, it's better to plan for shorter, 30-minute chunks.
(Omitted) The important thing is not to force yourself to hold a book and sit for a long time without concentration, but to divide your time into small chunks and concentrate as much as possible during that time.
--- p.78, from “[Short-term plan] If you have trouble concentrating, plan in 30-minute increments.”

The most important thing to keep in mind a month before the exam is to never approach it with the mindset of "I want to get the best score I've ever gotten."
Rather, let's think lightly that all we have to do is get the same score as in the previous mock exam without making any mistakes.
To do this, you need to minimize mistakes on the day of the test.
The more diligently a person studies, the more success or failure on the exam will be determined not by who gets more difficult questions right on the test day, but by who gets the same questions right without making any mistakes.
So when you take the test, you should think that you have answered all the questions correctly without making any mistakes.
